Inv. No. 337-TA-700
Contact: Peg O'Laughlin, 202-205-1819


The U.S. International Trade Commission (USITC) has voted to institute an investigation of certain surface mount MEMS devices and products containing the same. The products at issue in this investigation are micromachined structures such as microphones, accelerometers, and gyroscopes.

The investigation is based on a complaint filed by Analog Devices, Inc., of Norwood, MA, on December 1, 2009. The complaint alleges violations of section 337 of the Tariff Act of 1930 in the importation into the United States and sale of certain MEMS devices and products containing the same that infringe patents asserted by Analog Devices. The complainant requests that the USITC issue exclusion orders and cease and desist orders.

The USITC has identified the following as respondents in this investigation:

Knowles Electronics LLC of Itasca, IL; and
Mouser Electronics, Inc., of Mansfield, TX.

By instituting this investigation (337-TA-700), the USITC has not yet made any decision on the merits of the case. The USITC's Chief Administrative Law Judge will assign the case to one of the USITC's six administrative law judges (ALJ), who will schedule and hold an evidentiary hearing. The ALJ will make an initial determination as to whether there is a violation of section 337; that initial determination is subject to review by the Commission.

The USITC will make a final determination in the investigation at the earliest practicable time. Within 45 days after institution of the investigation, the USITC will set a target date for completing the investigation. USITC remedial orders in section 337 cases are effective when issued and become final 60 days after issuance unless disapproved for policy reasons by the U.S. Trade Representative within that 60-day period.
